Skipper Mark Pettini had made 42 while helping Bopara add 117 before he was forced out of the action with a back spasm.

Then Ryan ten Doeschate was forced to retire after being struck a bad blow on the hand by Jade Dernbach with just four runs against his name, although he did return to resume his innings at the fall of the eighth wicket.

But Bopara, who resumed on 83 this morning, was finally undone by paceman Pedro Collins when an intended drive was edged to Matt Spriegel at backward point, a dismissal that brought to an end a partnership of 130 with Tim Phillips.

Phillips contributed just 43 of those and needed just over three hours and 135 deliveries to complete his first half century for two seasons.

He eventually departed for 69 when he was caught at deep mid-wicket attacking leg spinner Chris Schofield after gathering eight fours and one six.

Further punishment on the toiling Surrey attack was inflicted by David Masters, who made 43, and then Kaneria, who struck three fours and two sixes while making 31 before Collins had him caught at deep extra cover.

Collins was easily the pick of the visiting bowlers, emerging with figures of four for 96 from 25.4 overs.

James Foster was handed the role of skipper in place of Pettini when Surrey went in again and elected to give the new ball to Kaneria.

It proved an inspired gamble as the Pakistan leg-spinner trapped Michael Brown lbw in his opening over before having nightwatchman Tim Linley snapped up in the slips from the last ball of the day.
